ABSTRACT:
The invention is a piston engine which has a plurality of cylinders, each cylinder having two ends in a first embodiment, and single ended in another embodiment, each end having a spark plug and inlet and exhaust valves. A distibutor is used for controlling the timing of firing the spark plugs and cams for controlling the operation of the inlet and exhaust valves. In each cylinder is a double ended piston. A transition arm is connected to each double ended piston by connecting shafts which extend into a central opening in each double ended piston. An adjustable flywheel is connected by a drive arm to the transition arm. Output from the engine is through an output shaft connected to the flywheel.
